Vegetarian cooking instructor Robertson (Vegan Planet ) turns her attention to the growing number of slow cooker owners. Starting with Slow Cooker Basics, she takes the user through the ins and outs of the appliance from the size of machine suitable for good results to cooking times and 10 quick tips for cooking success. She also devotes a small section to those vegetarian ingredients, such as seitan, that nonvegetarians may not be familiar with. Branching out from the traditional casseroles and stews so popular in the early days of the slow cooker, she tackles appetizers, soups and desserts as well, using the appliance with great effect to produce vegetable stocks as well as flavorful offerings like the Indian-inspired Curried Cauliflower Soup with Chutney and Cashews as well as Asian-influenced Hot and Sour Soup. The fundamental chilis and stews are not forgotten, but beans and grains—so essential to the vegetarian diet—put the slow cooker to best use. Pastas and vegetables nicely round out the book. (Jan.)
